If these new Advanced Forum Statistics Block take general information on members such as Latest Forum Pst, Hottest/Most Viewed Threads, Top Forum, Newest Members, Top Thread Starters, Top Reputations, it isn't a bad idea. But if they take specific information on members and then they are published, this could affect the privacy of the members and I don't like. However, I don't think these statistics are so intrusive, so I would say that I support them.
PS: I am a forum moderator but I cannot edit previous post after 2 minutes I wrote it. I think new forum moderator (as I) have too few powers of moderation, please give us more confidence.
